EMIL BRGIN, OF BASEL, SVITZERLAND.

MAGNETO-ELECTRIC MACHINE.

SPECIFICATION forming part of Letters Patent No. 224,642, dated February 17, 1880, Application filed June 14, 1STE).

To all whom t may concern:

Be it known that I, EMIL BRGIN, of Basel, in the Republic of Switzerland, have invented certain new and useful Improvements in Magneto-Electric Machines, of which the following is a specification.

The object of my invention is to produce a compact and simple machine for the production of alternative currents of electricity.

My invention consists in a novel construction of the generating-cylinder, in a novel combination of a commutator with said cylinder, and in certain details of construction hereinafter to he described.

In the accompanying drawings, Figure l represents a longitudinal section of a machine embodying my improvements; Fig. 2, a transverse section on the dotted line mfr, Fig. l; and Fig. 3, a perspective view of the several elements composing the generating-cylinder and their connections with the several commutator-rin gs.

Similar letters of reference designate correspondin g parts in all the iigures.

A designates the stationary frame of the machine, which may be made of wrought orv cast iron. It may be composed of two or several pieces, and is represented as wound with wire, forming coils a b c d c f g h, connected with each other so as to form poles B B C Cf when an electric current passes through them, and terminating at t'.

D designates a rotary generating-cylinder mounted on a central shaft, D, supported in bearin gs D2, extending from the frame A. The said shaft is also provided with a pulley, D3, which may receive a belt for rotating the said shaft and generating-cylinder. The generating-cylinder D is composed of a number of separate elements, 0 O 02 O3, represented as each consisting of a polygonal core or ring, j, which is preferably made of soft wire and which has its sides wound with insulated wire, forming coils 7c.

The core or ring j of each element is supported by arms l, radiating from a hub, on, upon the shaft D', which arms may be made of any metal other than iron. rBhe core or ring j of each element is shown as rectangular to correspond with the number of poles in the frame A; but it may be made in any polygonal form,

as hexagonal or octagonal, the frame A having its poles equal in number to the sides of the said core.

In order to make currents of electricity passing from the machine continuous the elements composing the generating-cylinder are set spirally on the shaft, each being a little in advance of the one at its side.

The manner of forming the coils 7tof insulated wire upon the cores or rings j is clearly illustrated in Fig. 3. The wire is wound in different directions on alternate sides of the` said cores or ring, and its two ends a o are connected to the commutator-rings, as hereinafter described.

The commutator shown consists of a sleeve insulated from and secured upon the shaft Dl so as to rotate therewith, and composed of a series of segments, p p' Ap2 p3, all insulated from each other and corresponding in number to the elements in the rotary generating-cylinder D. These segments have extending from them arms q, to which the wires o, leading from the elements of the generating-cylinder, are connected, the element O heilig' connected to the segment p, the elementO to the segment p', the element 02 to the segment p2, and the element O3 to the segment p.

E designates a ring insulated from and secured to the aforesaid segments so as to rotate therewith, and to which the wires n, leadin from the four elements of the generatingcylinder D, are connected.

The commutator F consists of a number of rings, i' r r2 r3, insulated from and secured upon the aforesaid segments, and also insulated from each other. Each ring, however, is connected with one of said segments, so as to receive the electric current therefrom, and the means here shown for effecting such connection consists of pins s, by which the said rings are secured to the several segments. rlhus the ring r is connected by Athe segment p with the element O, the ring` fr is connected by the segment p with the element O', and so on. It will thus be seen that the current ol" electricity passes from the commutator-linger t, bearing upon the ring E, to the several clements ot the generating-cylinder D, and from said elements passes to the several rings c" r r2 r3, and thence, through the commutator-iinlOO gers w w 11:21037away from the machine to the locality where needed.

I elaim as my invention- '"1" 1. The generating-oyliuder D, composed of the elements O O' O2 O3, arranged in helieal rela-tion with the shaft D.

Z. The connection of the coils 7c oi1 the elements with the commutator F.

3. The iron frame A, provided with the ooils a b e d e f g h7 which are Connected with each other so as to produce the poles B C B' C', sustantally as and for the purpose set forth.

4. In an electro-magnetic machine, the oombina-tion, With a genera-ting-oylinder composed of elements O O O2 O3, eaoh element consisting` of a polygonal ring or eo1e,j, having its sides Wound with wire, ofthe ring' E, with which all the elements are connected7 andthe rings o" 9" r2 T3, to which the said elements are connected separately through the segments 1J 29'192123, substantially as specified.
